Patented Got. '7, 1919.

Application filed January 26, 1915, Serial No. 4,416. Renewed September 4:, 1919. Serial No. 321,657.

To all whom it may concern Be it known that I, MICHAEL A. ROLLMAN, a citizen of the United States of America, and a resident of Mount Joy, county of Lancaster, State of Pennsylvania, have invented certain new and useful Improvements in Cherry-Stoners, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which- Figure l is a side elevation of a well known type of machine shown with my improvements applied thereto;

Fig. 2 is a plan view of the same;

Fig. 3 is a vertical transverse section on the line 2-2 of Fig. l; and

Fig. 4- is a perspective view in detail of one of the adjustable throat blocks.

This invention relates to that well known type of cherry stoner in which a ribbed wheel is rotated through a hopper in such manner that the stones are squeezed out of the fruit and delivered to a spout, while the pulp is delivered into a receptacle below the wheel, a pair of adjustable throat bars or blocks being employed on opposite sides of the wheel to enable the machine to be adapted to cherries having different sized stones; and the main object of the present invention is to improve and simplify the construction of the adjustable throat bars, to the end that they will be more efiective in operation, less liable to derangement and ca pable of being manufactured more economically, as more fully hereinafter set forth.

In the drawing, a designates the hopper, which, as usual, is made in two parts, fastened together by screws or rivets; and b designates the usual ribbed wheel journaled underneath the. hopper and working up through the same. In each side of the hopper is arranged an adjustable throat bar or block which consists olf a bar a grooved in the usual manner and provided with an outwardly extending arm (Z preferably rectangular in cross section. The arm (Z extends outwardly through a depending closed eye 6 formed integral with the adjacent half of the hopper.

The depending eye has an approximately rectangular opening through which the arm (Z passes, and the arm d is clamped in its adjusted position by means of a thumb screw 7 tapped down through the upper wall of the eye. The eye 6 is of suificient width to afiord a firm support for the arm d, and

the lower end of the thumb screw bears on the top side of the arm when the thumb screw is tightened. At each end of the throat bar 0 is formed integrally a rib g which lies approximately parallel with the arm (Z and projects outwardly from the bar a in the form of a pin. The ribs 9 fit in grooves in the adjacent end walls h of the usual notch formed in the lower end of the hopper for the reception of the throat block. In this manner it will be seen that each throat piece is supported at three points, namely, at the ends of the throat bar and at the point where the fiat arm d passes through the eye. This three-point way of supporting the throat piece is advantageous for the reason that a great degree of accu racy in fit is rendered unnecessary, thus enabling the parts to be cast in metal. It is the universal practice to make all the parts of these devices out of cast iron and it is important, therefore, that the parts be so constructed that they shall not only be interchangeable but they shall not require any machining operations. It will be seen, therefore, that my three-point support for the throat piece possesses an important ad vantage over devices in which the adjustable parts have extended flat contacting clamping faces, it being difiicult in casting to get these faces to always fit accurately.

Another and very important advantage in my device is that in view of the fact that the arms (Z are inserted through the eyes e from the inside and the throat bars 0 are too large to pass through the eyes, the throat pieces are made a permanent part of the apparatus when the two sides of the hopper are riveted together, since when the parts of the hopper are fastened the throat pieces .will be locked against removal even though the thumb screws, be disconnected or lost. This is an important advantage in view of the fact that the loss of one of these throat ieees renders the machine useless. It will e seen further that even if one of the set screws be lost, the throat piece can be locked by driving a small wedge into the eye. The set screws, however, will be in standard sizes so that they may be easily replaced if lost.

that the throat pieces are very easy to adjust, the adjustment being obtained by operating the set screw with one hand and grasping the projecting end of the arm cl Another advantage in my construction is device, this arm being thereby rendered selftightening. In the stoners ,of this type heretofore designed, the supporting arm or bracket has been pr vided with a clamp at its lower end and adapted to attach it to a table, said support extending upwardly and inwardly so as to discharge the stones and the pulp into dishes placed upon the table.

"lhis manner of supporting the device renders it somewhat unsteady and also so positions the crank that it is tiresome for some persons to'operate it for any considerable length of time. In my present machine, I cast the supporting member 76 on the under side of one of the hopper sections and provide the rear edge thereof with the usual clamp lug or plate Z and the usual clamp screw at. his depending supporting member 76 is much shorter than the supporting member heretofore in use, and, besides, is cast so as to project obliquely with reference to the main body of the n achine, thereby bringing the clamping members Z and 0% off to one side of a line drawn through the center of the machine. The result of this is that when the machine is clamped upon the edge of a table in the usual manner, the machine will project obliquely away from the edge of the table, as shown in Fig. 2, the

edge of the table oeing indicated by the dotted line a. l/Vith the machine in this position, the operator may sit on a chairadjacent to the table and have the machine in a very convenient position for turning the crank, so that the machine may be operated for long periods of time without serious fatigue. pulp and the pits may be conveniently placed on a chair positioned adjacent to the chair the operator is sitting upon.

It will be 0 served that another advantage in arranging the clamping aws Z and m on a line oblique to the center line of the ma 55.

chine lies in the fact that this arrangement permits the body of the machine to be located so low down with respect to the clamping jaws that when the device is clamped to a "table edge, the body of the machine will lie n the same horizontal plane with the table top, thereby not only making the machine compact and bringing the operating crank 'lhe receptacles for receiving the down to a position Where it may be conveniently manipulated, but also contributing greatly to steadiness, as compared with those machines which are mounted upon standards rising vertically from the table top and so arranged as to bring the machine at a distance above the table top.

Having thus described my invention, what I claim is:

1. In a cherry stoner of the type set forth, the hopper being proviced with depending eyes at opposite sides .of the wheel and a set screw in the top wall of each eye, and an adjustable throat piece at each side of the wheel, each throat piece consisting of a throat bar too large to pass through the eye and an outwardly extending arm working through the adjacent one of the eyes, for the purpose set forth.

2. in a cherry stoner of the type set forth, in which each side of the hopper is provided with a notch in its under ed 'e, the end walls of each notch being providedwith grooves, each side of the hopper being also provided with a depending eye and with a clamping thumb screw and adjustable throat pieces, each consisting of a throat bar provided with a rib at each end and also with an outwardly extending arm passing through one of said eyes, as substantially set forth.

3. In a cherry stoner of the type set forth, the hopper member being provided with depending eyes at opposite sides of the wheel and a set screw in one wall of each eye, and an adjustable throat piece at each side of the wheel, each throat piece consisting ,of a throat bar too large to pass through the eye and an outwardly extending arm working through the adjacent one of said eyes, said arm tapering outwardly, for the purpose set forth.

4c. in a cherry stoner of the type set forth, an integral supporting member depending from the bony of the ma hine at the rear end thereof and provided at its rear edge with integral jaws one of which carries means for clamping the edge of a table, said jaws be-' ing obliquely arranged with reference to the center line of the machine so as to offset them obliquely to the rear of the machine,
